How do commercial growers and/or supermarkets keep radishes so fresh?

Note: This isn't how to keep them fresh or freshen them up, I can Google that.

How do commercial growers or Supermarkets stop their radishes from going soft?
If you buy radish from the supermarket they stay firm and crispy for ages, a week at least. If you buy from a farm shop or pick your own from the garden they go dull and rubbery overnight.

So what are they doing to them?

    The temperature they store them at ?  Buying bagged or loose ?
    My home grown radish last longer than a day/night as will my beetroot.
    When I buy beetroot from organic farm shop, I can rely on 3 days ( or 4 at a push ) before they begin to feel a bit soft.  Not much difference from SM bought when I think about it. Still cook well at that stage.

    I have had the experience with buying crunchy SM radish and then loose organic ones that go soft in a day. If you are thinking of ones that come in sealed plastic bags, then the bags may have something that absorbs or mitigates ethylene.

    Rather like the Salad Bags the SM's sell I think @Fire ? They "puff" something in there to keep the leaves fresh/crisp.
    I suppose usually if you grow your own, you would pick for that day's lunch/dinner so always fresh and no time to deteriorate.
    Bit like walking round the garden/GH and scoffing half the fresh Toms before you even get back indoors to prepare the salad :D

    Possibly. Just guessing. Whatever they do helps radish keep very well

    Radishes sold in supermarkets are usually sold in ‘protective atmosphere’ bags … however they also have had their leaves removed. 

    Radishes sold on market stalls etc usually still have their leaves attached … these continue to draw  on moisture from the radish root so the roots soften.

    Radish without leaves soften and shrink. But you might expect that.

    Two weeks ago , my husband brought home some roses that a mate who works in the trade offered him. They were not up to standard for sale. Anyway, two weeks on, they're doing alright. It makes me wonder how old  the flowers you buy in the supermarket really are.
    Nice red. ridiculously long stems and no smell. Not ideal😒

    I keep my fridge very cold. Most vegetables last a long time. Whether or not nutrients are lost I don't know.

    Not if they’re in an airtight container. 😊

    As far as I know the bags are filled with nitrogen which does not support organic life, so deterioration caused by bacteria and fungi is dramatically slowed.
